Title: Manufacture of printed wiring board
Inventor: KAWADE MASAHITO
IPC: H05K3/18
Filed: 1992-04-20
Abstract: PURPOSE:To prevent exfoliation at the time of mounting a component and to ensure sufficiently high bonding strength of a conductor by preheating a board prior to application of plating resist. CONSTITUTION:An insulating board 1 is subjected to surface abrasion to provide a roughened surface 2 onto which an adhesive is applied and then dried and cured to form an adhesive layer 3. It is then immersed into chromic acid where fine powder or epoxy resin is dissolved and removed thus roughening 4 the surface of the adhesive layer 3 and thus roughned surface 4 is subsequently activated to impart catalytic nucleus onto the surface of the board. Subsequently, it is subjected to heat treatment and a dry film is laminated on the board imparted with catalyst. The resist laminated board is then exposed, heat treated and developed to form a plated resist 6. It is subsequently immersed into electroless plating liquid in order to form a conductor circuit 7. This method keeps up followability of dry film resist into an anchor, suppresses residual bubbles, and prevents exfoliation at the time of mounting a component.

IPC: F24F6/18
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To sufficiently humidify by slight steam humidification by water- humidifying the atmosphere or the air obtained by mixing the atmosphere with returned air and then steam-humidifying it to feed it into a room in the case of introducing the atmosphere in the state that the atmospheric temperature is lower than that indoor and cooling a room with cold heat of the atmosphere. SOLUTION: The outdoor air OA and return air RA introduced into an air conditioner casing 1 are mixed by a mixing chamber 2, air conditioned to a predetermined temperature via a cooling coil 3, then sequentially passed through a water humidifier 10 and steam humidifier 12 to become supply air SA of a predetermined humidity, and the air SA is supplied to respective rooms of a building via a duct by a fan 5.

Title: Boiler device
Inventor: OIKAWA MASAO
IPC: F23D11/10
Filed: 1981-08-19
Abstract: PURPOSE:To improve combustion at a starting time when the temperature of the can of a boiler is low, by providing a selector valve to open and close a feed passage to feed gas and steam to an oil burner, as well as to enable a gas atomizing medium to be fed to the oil burner of a boiler. CONSTITUTION:A selector valve 18 is opened and a gas burner 6 is ignited. Then, when a selector valve 10 is opened, gas from a gas bomb 8 is fed into a fuel atomizer 1a of an oil burner, passing through a piping 7 and an atomizer piping 9, and is injected from an oil burner 1. With the gas being injected, the oil burner 1 is started to burn, as well. At this time, when fuel oil is fed into a fuel atomizer 1a from a hydraulic pump 2, the oil is atomized by the pressure of gas, and mixed combustion of oil and gas is started, so that combustion on the oil burner 1 is taken place in good condition. In such a manner, combustion can be performed in good condition at the starting time when the temperature of the can of a boiler is still low. Further, the cost of power and an installation cost of the combustion apparatus can remarkably be reduced, since a hydraulic pump to feed fuel oil is not necessary, and piping of low pressure type can be used for this type of boiler.

Title: Magnetic powder dispersed type microcarrier
Inventor: KASUYA RIYUUHEI
IPC: G03G9/08
Filed: 1984-06-25
Abstract: PURPOSE:To enhance cleanability, electrostatic charging controllability of a toner, fluidity, and image quality by incorporating the stirred mixture of a carrier powder specified in average particle diameter contg. a fine magnetic powder dispersed into a binder resin, and a cleaning adjuvant. CONSTITUTION:The cleaning adjuvant is stirred and mixed with the carrier powder having an average particle diameter of 10-50mum prepared by dispersing the fine magnetic powder into the binder resin. The use of the small-diameter carrier can enhance toner concn. and enlarge its allowance, so visible images high in density can be obtained stably. Since each bristle of a magnetic brush in the magnetic grush development can be formed properly delicately and softly, the obtained visible image is good in sharpness and gradation and high in reproducibility. Further, since the carrier contains the cleaning adjuvant, the powder remaining on a latent image bearing body can be securely removed, and even a small content of the cleaning adjuvant it has an effect, and it does not hinder the charging controllability of the toner, thus permitting an image good in image quality to be obtained.
